JACOB KAUFMANN, 0F PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO STEEL IHEDDLE MANUFACTURING 'COMPANY, I VANIA, A CORPORATION OF PENNSYLVANIA.

OF PHILADELPHIA, PENNSYL- HEDDLE-FRAME.

Specification of Letters Patent. Patented Nov. 16, 192(1).

Application filed September 3, 1919. Serial No. 321,305.

To all whom it may concern Be it known that I, JAooB KAUFMANN, a citizenof the United States, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania have invented certain new anduseful Improvements in Heddle-Frames, of which the following is aspecification.

My invention relates to heddle-frames for looms, and it relates moreparticularly to.

firmly support the heddle bars intermediate their ends, thereby insuringfreedom and easy play of the heddles on the heddle bars.

My invention contemplates a form of stay or brace which can be readilyand easily attached in and detached from the frame, and which is soconstructed and arranged as 'to effectively function for its intendedpurpose, while at the same time permitting the proper arrangement of theheddles in the frame. My present invention'is particularly applicable tothat type of heddle frames in which there are provided single heddlebars at the top and bottom of the frame.

The nature and characteristic features of my invention will be morereadily understood from the following description taken in connectionwith the accompanying drawings, forming part hereof, in which;

Figure 1 is a front elevation of a heddle frame provided with a stay orbrace embodying the .main features of my present invention' Fig. 2 is anenlarged fragmentary detail view, partly in elevation and partly insection, of a portion ofthe structure shown in Fig. 1, illustrating themanner of connecting the stay rod to the top and bottom rails of theframe; and

Fig. 3 is a transverse section thereof, taken on approximately the line3-3 of Fig. 2, certain portions being shown in elevation.

Referring to the drawings, the heddle frame there shown comprises thetop, and bottom rails 5, usually made of wood, and connected at theirres )ective ends by means of'the end strips 6. *Xtending from endto endof the heddle frame, and arranged near the top and bottom rails in theusual manner are the heddle bars 7, upon which the heddles 8 are mountedand supported.

The stay rod proper comprises a thin flat strip of metal suitablylocated in the heddle frame at desired places intermediate the endsthereof. Each end of the stay rod 9 is centrally slotted as at 10 toprovide a recess within which the heddle bar 7 is supported againstsidewise displacement and also against displacement toward the center ofthe frame, so that when tension comes on the heddles as the shed isformed the heddle bars 7 will be properly maintained in position.

The slot 10. at each end of the stay rod 9 I is provided with an.enlarged portionll,

which is engaged by a hook like extension 12 formed on the inner end ofa bolt 13 which passes through the rail 5. The other end of the bolt 13is threaded to receive a complementally threaded nut 14:, preferably ofthe wing type. A washer 15is arranged on the bolt 13 on the outer sideof the rail 5, and a split lock washer 16 is interposed between thewasher 15 and the nut 16.

A metal plate 17 is suitably located on the inner edge of the rail 5,the bolt 13 passing therethrough. The plate 17 is provided with a slot18 in which are positioned lugs or extensions 19 which areformed on theend of the stay rod or brace 9, one on each side of the slot 10. Thepurpose of the foregoing arrangement is-to positively position the endsof the stay rod 9 in the frame, and also to prevent spreading of thesame when tension is applied by advancing the wing nut 14: on the bolt13, as it will be seen that otherwise the hook like extension 12 wouldtend to spread the bifurcated end of the stay rod 9.

It will be noted that with a device con- I structed and arranged asaforesaid, the stay or brace 9 may be readily removed forthe purpose ofre-arranging the heddles mountslot 18 of the plate 17, which is carriedon the inner edge of the rail- 5, whereupon, the stay or brace 9 may bereadlly shifted with respect to said securing device, and, by rea son ofthe slot 10 being open to the end of' thestay rod 9, said stay rod maybe readily disengaged from the heddle bar 7 which is supported in saidslot 10 thereof.

It will be seen that there is thus provided a simple and efiicient formof stay or brace, and means for securing the same intermediate the. endof the heddle frame, which will effectively function to preventspringing of the top and bottom rails, which will also support theheddle bars and maintain the same in proper positions, and which may bereadily removed when desired, for the purpose of permitting theinsertion or rearrangementof the heddles upon the heddle bars 7.

Having thus described the nature and characteristic features of myinvention what I claim as new, and desire to secure by Letters Patentis: l

1. In a heddle frame, top and bottom rails, heddle supporting bars, astay rod arranged intermediate the ends of the frame, said stay rodhaving slots at its ends in which the heddle bars are supported, meansmounted in said top and bottom rails adapt ed to drawthe ends of thestay rod toward the top and bottom rails, and members mounted on theinner edges of the top and bottom rails adapted to be engaged by theends of the stay rod.

In testimony whereof, I have hereunto signed my name.
